Answer:
5437.5 N
Explanation:
from the question we are given the following:
mass = 7.25 kg
initial speed (u) = 10.5
finial velocity (v) = 0
compression (s) = -7.35 cm = -0.0735 m (the negative sign is because the face is compressed, so there is a decrease)
we know that force = mass x acceleration,
we have our mass but need to find the acceleration. we can get the acceleration by applying the formula below
therefore
0 = 10.5^{2} + (-2)× a × 0.0735[/tex]
a = }[/tex]
a = 750
from F = m x a
force = 7.25 x 750 = 5437.5 N
Answer:
Explanation:
We know that, the force responsible for circulating in circular path is the centripetal force given by the force on charged particle due to magnetic field.
Here the charge is antiproton is
p = -1.6 * 10⁻¹⁹C
the speed of proton is given by 1.5 * 10 ⁴ m/s
the magnetic field is B = 4.5 * 10⁻³T
we have force due to magnetic field is equal to centripetal force
Bqv = mv² / r
Bq = mv / r
The diameter d of the vacuum chamber have to allow these antiprotons to circulate without touching the walls is
d = 2r
d = 2 * 3.479
d = 6.958
d ≅ 7cm
